I bought this pedal for the keyboard player in our band although I don't play keyboard myself. I was fed up with his varying volume levels. He was either drowning out the singer or you couldn't hear him at all. Although it appears to be made of mainly plastic components, it was reasonably cheap and it seems to work ok. It's anybody's guess how it will stand up to a lot of use but we don't go out much, and it's cheap enough to replace. Hopefully if he gets used to it he might feel motivated to buy a better one himself. I live in hope. The only real downside is the lack of instructions with it (none). I appreciate that there isn't much to it, but a bit of guidance as to how to set the volume level would have been useful. We've managed to work it out by adjusting the little rotary dial on the side, but we found that if you set this too high initially then the pedal doesn't actually seem to do anything. By setting it about a third of the way up and cranking the pedal off, we found we could set the PA level for what we wanted from him as his minimum volume. Pushing the pedal fully forwards then caused the required increase in volume so he can now adjust his output depending on whether he is accompanying or soloing. There are 2 standard jack inputs (1 & 2) and 2 outputs (also 1 & 2), presumably for stereo use, although we just bring the one lead out of the keyboard into input 1 and then another lead to the PA from output 1. Once set up like this, his overall sound can still be adjusted at the mixer, while still keeping the same margin of difference between the pedal positions. A useful product.
It took maybe one month before one of the stereo channels started to wear out. It started to make loud noises when volume was turned almost down. It was squeaky aswell. It feels very plastic and not rigid at all, and didn't have any of that resistance you feel when you change volume on a quality expression pedal. You can't use the pedal with a high impedance signal, like a guitar, but that should be quite obvious if you read the description for the pedal. But It does actually have a nice rubber surface for the foot to rest on. I wouldn't recommend this pedal to anyone. Straight to the trash can. But it was very cheap, so I can't really complain.
